<https://github.com/ricardo-bion/ggtech>
ggplot2 tech themes, scales, and geoms.
```{r, message=FALSE,warning=FALSE}
# Example from https://github.com/ricardo-bion/ggtech
library(ggplot2)
library(ggtech)
# Make sure to install the required fonts
# (instructions at the end of this file).
extrafont::font_import(pattern = 'Guardian-EgypTT-Text-Regular.ttf', prompt=FALSE)
d <- qplot(carat, data = diamonds[diamonds$color %in%LETTERS[4:7], ], geom = "histogram", bins=30, fill = color)
```
Tech themes and scales:
```{r}
d + theme_tech(theme="airbnb") + ggtitle("Airbnb ggplot2 theme") + scale_fill_tech(theme="airbnb")
```
```{r}
d + theme_tech(theme="etsy") + ggtitle("Etsy ggplot2 theme") + scale_fill_tech(theme="etsy")
```
```{r}
d + theme_tech(theme="facebook") + ggtitle("Facebook ggplot2 theme") + scale_fill_tech(theme="facebook")
```
```{r}
d + theme_tech(theme="google") + ggtitle("Google ggplot2 theme") + scale_fill_tech(theme="google")
```
```{r}
d + theme_tech(theme="twitter") + ggtitle("Twitter ggplot2 theme") + scale_fill_tech(theme="twitter")
```
Tech geoms, inspired by [emoGG](https://github.com/dill/emoGG).
```{r}
d2 <- data.frame(x = c(1:4, 3:1), y=1:7)
```
```{r}
ggplot(aes(x,y), data=d2) +
geom_tech(size=0.25, theme="airbnb") +
theme_tech("airbnb") +
ggtitle("Airbnb geom")
```
```{r}
ggplot(aes(x,y), data=d2) +
geom_tech(size=0.15, theme="etsy") +
theme_tech("etsy")+
ggtitle("Etsy geom")
```
```{r}
ggplot(aes(x,y), data=d2) +
geom_tech(size=0.15, theme="facebook") +
theme_tech("facebook")+
ggtitle("Facebook geom")
```
```{r}
ggplot(aes(x,y), data=d2) +
geom_tech(size=0.25, theme="google") +
theme_tech("google" ) +
ggtitle("Google geom")
```
```{r}
ggplot(aes(x,y), data=d2) +
geom_tech(size=0.15, theme="twitter") +
theme_tech("twitter") +
ggtitle("Twitter geom")
```
